In a July cover article titled “The Web Means the End of Forgetting,” the New York Times Magazine explored how the Internet is changing privacy. Recently, the Wall Street Journal reported on Google’s “soul-searching” over the question of how far to go in “profiting from its crown jewels -- the vast trove of data it possesses about people’s activities.”
Rohini Srihari, who teaches classes on Web search and mining and is founder and CEO of Janya Inc., a text analysis/text mining firm, understands the potential of data mining -- and the complicated concerns it raises.Rohini K. Srihari
Srihari: Practically everyone. The telecoms, credit card agencies, major retailers, airlines, e-commerce providers like Amazon -- all of these entities are engaged in data mining. One emerging technology is socially targeted advertising. Companies that provide this service analyze the browsing patterns of brand loyalists, identify Internet users with similar browsing patterns, and use that information to target advertising. The success stories of companies attracting new customers through socially targeted advertising are amazing.What are some interesting challenges that researchers and companies face when mining data on the Web?
Srihari: The No. 1 challenge is balancing privacy with data mining. We’ve come to a stage where we do less than we can for fear of spooking the public. How do you gain enough information to help a retailer without creating a backlash? You don’t want people to feel like you’re invading their privacy. There are technical challenges, like making sense of text with multiple languages or spelling mistakes, but it’s achieving that balance between data mining and privacy that is the No. 1 challenge.

Staphylococcus aureus is a feared pathogen (MRSA, multi-resistant S. aureus) due to frequent resistances against many antibiotics, especially in hospital infections. Researchers at the Paul-Ehrlich-Institut have identified immunological processes that prevent a successful immune response directed against the pathogenic agent. The delivery of bacterial proteins with RNA adjuvant or messenger RNA (mRNA) into immune cells allows the re-direction of the immune response towards an active defense against S. aureus. This could be of significant importance for the development of an effective vaccine. PLOS Pathogens has published these research results online on 25 May 2017.
Staphylococcus aureus (S. aureus) is a bacterium that colonizes by far more than half of the skin and the mucosa of adults, usually without causing infections....
Physicists from the University of Würzburg are capable of generating identical looking single light particles at the push of a button. Two new studies now demonstrate the potential this method holds.
The quantum computer has fuelled the imagination of scientists for decades: It is based on fundamentally different phenomena than a conventional computer....
An international team of physicists has monitored the scattering behaviour of electrons in a non-conducting material in real-time. Their insights could be beneficial for radiotherapy.
We can refer to electrons in non-conducting materials as ‘sluggish’. Typically, they remain fixed in a location, deep inside an atomic composite. It is hence...
Two-dimensional magnetic structures are regarded as a promising material for new types of data storage, since the magnetic properties of individual molecular building blocks can be investigated and modified. For the first time, researchers have now produced a wafer-thin ferrimagnet, in which molecules with different magnetic centers arrange themselves on a gold surface to form a checkerboard pattern. Scientists at the Swiss Nanoscience Institute at the University of Basel and the Paul Scherrer Institute published their findings in the journal Nature Communications.
Ferrimagnets are composed of two centers which are magnetized at different strengths and point in opposing directions. Two-dimensional, quasi-flat ferrimagnets...
